Stat6640 R Codes & Data Sets for 2-Level Designs Spring 2015

R codes for functions used in this handout (including halfnormal
plot, chaiquare plot and cubeplot) and, in addition, the Lenth
critical values Lenth.IER and Lenth.EER:
fact2.R.
Source this R code only once (for your convenience, I placed
a save.image call at the end). You can do this within R bysource("http://www.stat.wmich.edu/wang/664/notes/2Levels/fact2.R")
